SHUTTLE.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed March 29, 1917. Serial No. 158,167.

To all whom it may concern Be it known that I, WVILLIAM H. WILSON, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Shuttles, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttles and pertains more particularly to a threading device by which the thread may easily be positioned and will be guarded against dethreading during the run or movement of the shuttle.

The invention consists of a combined eyeguard and tensioning device made. of wire and so formed, coiled and the parts related whereby the thread will be directed into the eye and positively prevented from accidental removal therefrom, at the same time maintaining the proper tension on the thread as the shuttle is operating.

The invention further resides in an improved delivery eye formed of a single length of wire having a shank extending into an opening in the shuttle body for being offset to constitute a means by which said eye is secured in position.

In the drawings Figure 1 is a fragmentary plan view of the threading end of a shuttle embodying the present invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a transverse section on line 33 of Fig. 1.

Fig. 4 is a perspective of the thread guiding member.

Fig. 5 is a similar view of the delivery eye.

Fig. 6 is a perspective view of a guard.

Referring more in detail to the drawing, the numeral 1 designates the. shuttle body having the usual bobbin chamber 2 in which is located a bobbin 3. The usual shuttle eye 4 leads laterally from the forward end of the bobbin chamber and from the inner end of the eye extends a vertical opening 5. The usual threading slits 6 and 7 are provided for threading the bobbin cord or thread into the eye. a.

The delivery eye comprises a single length of wire of right angular formation having its shorter arm 8 terminating with an inturned sharpened point 9, while its longer arm 10 is bent, adjacent the shorter arm 8, to provide a lateral Ubend 11, which U-bend is coiled to form a complete eye, the base or connecting portion ofthe U being-disposed in the plane of the arms 8 and 10 and in spaced relation thereto.

The thread guiding member is also formed of a singlelength of wire bent at right angles to form a shorter arm 13 and a-longer arm 14, the former terminating in a downturned securing spur 15. The longer arm is coiled midway to provide a transverse loop 16 having an entrance opening 17, and the 'free end of said longer arm is sharpened as in 18.

The shuttle body is formed with a vertical opening 19 which is connected at its lower end by a passage 20 with the eye a. The delivery eye is positioned in theshuttle eye opening 4: with its longer arm or shank 10 passing through the connecting passage 20 and across the opening 19 into the body of the shuttle, as depicted in Fig. 3. During the positioning of this delivery eye, the barbed end 9 is driven into the shuttle body below the threading slit 7, the shank 10 and passage 20 being also disposed in a plane beneath said slit. A tool is then inserted in the opening '19 for offsetting the shank 10 to form a crimp 21 which obviously locks the delivery eye inposition.

The thread guiding member is inserted through the vertical opening 5 and secured in position-by forcing the barbs 15 and 18 into the shuttle body, as shown in Fig. 3, the barb 18 passing inside'the shank 10, and the upper portion ofthe longer arm let inclined across the threading slit 6 into a vertical groove23 formed in the wall of the vertical opening 5. The loop 16 is disposed horizontally and-in the plane of the upper part 'ofthe U11.

A guard 24 in the nature of a staple is driven into the shuttle body to extend across the upper end of-the groove'23', said; guard also serving as a guide in the process of entering the thread in slit 6.

It will thus be seen that when the thread is entered between the guard 24 and the guiding member and into the slit 6, the thread may then be manipulated through slit '7 against the delivery eye where the U- bend' will deflect the thread downwardly beneath sai bend and into the coil defined,

by the latter. Therefore, the thread in its normal position leads from the bobbin through the loop 16 and out through the delivery eye.

It will further be noted that by crimping the shank 10 the delivery eye is positively locked against dislodgment without the aid of additional parts or securing means. All the parts may be easily and cheaply manufactured from wire, the length having their terminals sharpened, preferably, to permit of the devices being easily anchored to the shuttle.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A loom shuttle having a transverse passage through the wall thereof and through which the thread passes, said shuttle also having a vertical opening connected at its lower end with the transverse passage, and a delivery eye disposed within the passage of the shuttle and having a part extending completely across the opening thereof and crimped thereinto to lock the eye in position.

2. In a shuttle, a shuttle body having a transverse eye passage, a vertical opening leading upwardly from the inner end portion of the passage, and threading slits connecting the passage and opening through the walls of the body, the vertical opening having a groove in its wall, a delivery eye secured in the eye passage of the body, a vertically disposed thread guiding member in the vertical opening of the body having an inclined part extending into the groove of said opening, and a staple-shaped guard secured to the body across the upper end of the groove of the vertical opening, said delivery eye, thread guiding member and guard all being formed of wire.

3. A shuttle body having a transverse eye passage, a communicating vertical opening and a connecting threading slit between the two, a thread guiding member in the body 'opening comprising a lower shank portion carrying a horizontal loop upwardly from which extends an upper shank portion, said upper shank portion forming an overhanging shoulder above the lower shank portion to aid in engaging the thread in the loop.

4. In a shuttle, a shuttle body having an eye passage, and a delivery eye member se cured in the passage and consisting of a single length of wire bent to provide shank and arm portions, the intermediate portion of which is bent laterally, and then given a return bend to form a Ushaped loop the sides of which lie in the plane of the shank, the free terminal of the wire being extended at right angles to the shank and to the loop to provide a securing arm, said loop being coiled in the direction of the arm and terminating in the plane, including the latter and shank.

5. A shuttle body having a transverse eye passage, a communicating vertical opening and a connecting threading slit between the two, a wire thread guiding member disposed in the body opening and comprising a single length of wire bent into angular formation at its upper end to provide a securing member and a downwardly extending inclined shank portion that is bent into a horizontal loop and then extended down in the form of a securing barb, said inclined shank overhanging the barb to provide a shoulder beneath which the thread is engaged to aid in guiding it into the loop.

6. In a shuttle, a shuttle body having an eye passage and a threading slit leading thereto, and a delivery eye member formed of a single length of wire to provide a shank portion and a right angular arm, the latter extending beneath the threading slit and secured to the body and the shank bent substantially parallel with the arm to provide a laterally extending eye-forming part which is coiled into eye formation.

7. In a shuttle, a shuttle body having a delivery eye passage and an angularly related opening communicating therewith, and a delivery eye having a wire shank extend ing across the body opening and into the body, said shank part that extends across the body opening being crimped therein at a point intermediate its ends to lock the eye against displacement.

8. In a shuttle, a shuttle body having an eye passage, a vertical opening communicating therewith at its inner end, and a threading slit connecting the two, a delivery eye formed of wire and having a shank lying beneath the slit in the passage, and a thread guiding member vertically arranged in the opening of the body and having a shank passing into the body adjacent the first shank, said second shank being formed with a horizontal loop opened at its side remote from the delivery eye.

9. In a shuttle, a shuttle body, a delivery eye member secured thereto, and a thread guiding member formed of wire and vertically disposed in the body, said thread guiding member consisting of a shank bent between its ends to form a horizontally disposed loop with shank portions above and below the loop secured. to the body.

10. In a shuttle, a shuttle body having an eye passage and an angularly related communicating opening for receiving a crimping tool and extending beyond the eye passage, and a delivery eye member formed of wire and having a shank extending through the body opening and terminating short of the adjacent side of the shuttle body for being crimped to interlock with the wall of the body opening.

11. A. shuttle having a laterally opening delivery eye passage and a vertical tool-receiving opening extending through the top In testimony whereof I have signed my of the shuttle and spaced from the inner end name to this specification in the presence of of the passage, and a delivery eye arranged two subscribing Witnesses.
